100G Ethernet includes a process that continually monitors the performance of received PCS data and triggers an alarm condition in the event that an excessive error ratio is detected. When receiving data at the PCS each lane is checked for errors in the 2 bit sync header in each 66b block. A counter is maintained…(Read More)
Unlike previous pluggable transceiver modules there is a real requirement to test the CFP in a staging area prior to deployment. Previous devices such as the SFP or XFP currently are available with commodity pricing from almost $50 to a a few thousand dollars depending on the required interface support. In comparison the CFP can…(Read More)
The alignment marker is used for the identification of the PCS lanes. They allow the receiving network equipment to identify the lanes as they are received so that that they can be re-ordered. So what is an alignment marker? An alignment marker is a single 66 bit block that is inserted into the stream…(Read More)
